How to operate the Sound Adjustment Mode
A variety of materials are used inside a vehicle to manufacture
the seats and windows, and because these materials absorb
and reflect sound in different ways, the parametric equalizer
lets you adjust the peaks and dips of the frequency
characteristics inside the vehicle to compensate for this.
An "equalizer" is a function that corrects these peaks and dips
in order to flatten the frequency characteristics. However with a
normal graphic equalizer, the median frequency and the Q
(sharpness and band width) are fixed, so that when
neighboring bands are corrected, there is a limit to the amount
by which distortion in the peak and dip characteristics can be
corrected.
A "parametric equalizer" lets you adjust the median frequency,
Q (sharpness and band width) and gain to variable levels, so
that you can make fine adjustments to spot areas of the
frequency band.

The graphic equalizer lets you select from six preset equalizer
modes in accordance with the genre and instruments of the
music being played, and also lets you make fine adjustments
within each mode.
